FARM-GATE.

SPECIFICATION forming part of Letters Patent No. 422,491, dated March 4, 1890.

Application tiled May 29,1888. Renewed February 3, 1890. Serial No. 339,059- (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. BEARDs- LEE, a citizen of the United States, residing in Berkeley, in the county of Alameda and State of California, have invented an Improved Farm-Gate; and I hereby declare the following to be a full, clear, and eXact description thereof.

My invention relates to certain improvements in the construction of lthat class of self-closing farm-gates in which the gate may be opened without the necessity of alighting from a vehicle.

The objects of my invention are, first, to provide a farm-gate of simple, durable, and

cheap construction, which can be opened from4 a passing vehicle without the necessity of alighting; second, to arrange it so that the shrinkage of the gate from the seasoning effeet of the weather can be adjusted so as not to interfere with the operation of the latching device; third, to provide m eansin the device whereby the sagging of the outer end of the gate may be counteracted; fourth, to provide means for preventing unlatching by the bodily lifting of the gate. I accomplish these objects by means of the devices illustrated in the accompanying' drawings, in which-f- Figure 1 is an isometrical view of the gate in position showing thev arrangement of the rope. Fig. 2 is a front elevation, portions being broken away to illustrate my invention more clearly. Fig. 8 is an isometrical view of the latching device with the means of compensating for the contraction of the gate. Fig. 4 is an isometrical view ofthe unlatching device. Fig. 5 is au isometrical View showing the manner in which the sag of the gate is counteracted.

Like letters refer to similar parts in the various views.

Referring to the accompanying drawings, A is the gate.

A is a rope by means of which the gate is opened; A2, cord or wire for operating the latch; ct a, handles on the ends 'of rope A; a2, guide-rollers for rope A a8, weight or coun-s ter-balance; B, pivoted lever; B', friction-l roller in B; B2, slotted plate-guide for B 5 b, pivot-pin for B; b', hole in B for attachment of rope A b2, hole in B for attachment of latch-cord; C, pivoted latch; C', pivot of lthe post.

Then the rope A is pulled, its iirst action is to draw the pivoted lever B backward, the friction-roller B causing the lever to work easily. The leverv B being attached to the latch by means of a wire or cord, as shown at@ in Fig. 3, the motion of the lever B raises the latch out of the sneek. or catch. The latch being raised to its limit of motion, the further pulling of the ropeA causes the gate to open toward the approaching vehicle. When the gate is opened to its fullest extent, the latch c engages with the sneek or hook D', and so secures the gate in this position. Vhen the vehicle has passed through and it is desired to close the gate, by pulling on the other end of the rope the lever B is drawn back and the latch again raised, thereby allowing the gate sneek or catch D is secured to the gate-post by two bolts, which pass completely through These bolts are furnished with a number of washers, which, when the gate is iirst put up,are on the end of the bolt farthest from the gate; but as the gate shrinks their position is reversed, one or more, as the amount of shrinkage requires, being placed between the sneek. or catch and the post, thereby carrying the sneek into correct position for engaging with the latch.

. The upper hinge or pivot is secured to the gate-post by means of a threaded bolt or stud, which passes completely through the post, its end being furnished with a nut and Washer. A portion'of its length, commencing from its hinge-pivot, is made square, the hole through which it passes being also made square to fit the square portion ofthe bolt. A plate or shield is attached to the post on the side nearest the gate, having a square hole through which the bolt passes, the square part of the IOO bolt fitting snugly into it. By means of this device the which invariably takes place at the outer end of a gate is counteractod by simply drawing the hinge E nearer to the post by means of the nut. The lower hinge being stationary, the end of the gate is thereby elevated.

It is evident that when the rope A has pulled the gate open to such a position that the pull of the rope is at right angles to the gate its action on the latch ceases, and the latch being of considerable Weight falls to its normal position, being thus ready to engage with the sneek or hook D when the gate is drawn full opent The lug c'l at the lower end of slotted guide-plate C2 prevents the opening of the gate through other means than the tilting of the latch.

Having now described my invention, what I claim as new, and desire te secure by Letters Patent, is-

l. In a self-closing gate, the combination of the gate A, the pivot of the upper hinge of which is located forward. of a vertical line passing through the pivot ol thelower hinge, the double-ended snccl: or catch l), with its `bolts l (l and. adjlisting-washers (Z, pivoted latch C,with its lug o, the slotted guide-plate 2, with its lug ci, cord A2, pivoted lever l, with its friction-roller B, the rope A', with its guide-rollers suitably supported on posts, and its counter-weights a3 a3 and handles o. a, substantially described.

2. In a self-closing gate, the gate A, the pivot of the upper hinge of which is located forward of a vertical line passing through the pivot of the lower hinge, the adjustable hinge E,with.its shield or guide-plate e', the rope A with. its counter-weights a3 a, handles a u, and guiderollcrs amg', suitably supported, the pivotcd lever l, with its friction-roller ll and guide-plate B2, pivotcd latch C, guide-plate C?, with its lug c, cord A2, connecting pivoted lever B with latch C, the double-ended sneek. or catch l) with its bolts d cl and adjustingwashers fl d', and the snecks or hooks D D', all arranged and operating substantially as described.
